IMPROVEMENT IN DEVAPORIZING APPARATUS.

Specification forming part of Letters Patent No. 170,844, dated December 7, 1875; application iiled October 29, 1875.

To all whom it may concern Beit known that I, LEVI K. FULLER, of Brattleborough, in the county of Windham and State of Vermont, have invented certain Improvements in Devaporizing Apparatus, of which the following' is a specification My invention relates to that class of appal ratus in which the moisture held in suspension by the warm air of a dry-house is condensed upon the surfaces of pipes containing cold water, or through which cold water is caused to pass; andit consists, essentially, in groups of pipes--two or more in each groupwith drums or cross-pipes across' the ends of each group, each drum connecting with the next adjoining, at opposite ends of the groups, alternately, as clearly shown. Each pipe of the group may be provided with an elbow at the lower end, as shown.

Iam well awarethat single serpentine pipes, with streams of cold water passing through them, have been used for this purpose, but these are very defective in practice.

With a low hydrant pressure, the excessive friction in the pipe renders the dow uncertain, and if only a trifling amount ot' air accumulates in the pipes-which is inevitable-it causes serious trouble. y

To obviate these defects, and, at the same time, provide ample4 condensingsur'ace, are the object-s of this invention.

In the drawings, Figure l is an interior view ot' a dry-house, showing my improved apparatus in side elevation. Fig. 2 is a sectional view in the plane ofthe line .1: m, Fig. l, and at right angles to the said ligure.

Let A represent any form of' dry-house, and BB groups of condensingpipes, here shown grouped in threes, and placed vertically. The

pipes a a of each group are tied at the top and bottom by connection with drums or cross-pipes C C, which should be of a suitable diameter to receive the pipes a a. D D are pipes connecting the adjoining pipes C C at opposite ends of the groups, alternately. E is the inlet pipe, by which cold water is admitted to the groups of pipes, and F the outlet.

The groups may be supported in position by the means shown, or in any other convenient manner. i

The water, entering at E, passes down through the first group of pipes, up throughV the second, down` through the third, and so on to the outlet-the number of groups depending, of course, on the capacity of the dry-house.

An inclined trough, Gr, may be arranged beneath the lower pipes O G, to catch and convey the water of condensation out of the dryhouse. c c are elbows, by which the pipes a a are connected with the pipe C. If the pipes a a are to enter the pipe C at the top, these will be omitted.

I claiml. The combination of the vertical pipes a a, grouped as shown, with the elbows cc and cross-pipes C C, in the manner specified.

2. The combination ofthe pipesa a arranged in groups of two'I or more, with the pipes C C, DD, E, and F, substantially in the manner and for the purposes specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
